One record across five programs

The five programs each run the same five stages. This sets out all twenty-five combinations: what happens at that stage for that program, what it produces, and whether law or district choice governs it.

Source. The program matrix and the entitlement timeline are generated from the product’s own registries, which are the same tables the software runs on.Where a claim carries no verified citation the badge says so rather than the page implying one.

Each cell names the stage and the authority that governs it. The numbered notes below the grid give the work and the artifact it produces.

One record beneath all five. The line is continuous because the record is.

The chain joining the five markers is the shared record. The chain is continuous because the record is; hovering a row brightens its star and the segments it touches.

measured 21 verified · 3 no-citation · 1 practice — citations resolve against the product’s own registry, and each carries its verification status.

The timeline is drawn to scale from age 3 to the end of entitlement. Each marker states its authority and how that authority was verified; three of them are not settled law, and say so.
One record, to scale — age 0 to the end of entitlement
  1. age 3 Part C → Part B StatuteWAC 392-172A-02080 — transition from Part C to preschool (Part B) Early-intervention services hand off to school-district special education. The evaluation decision has its own school-day clock.
  2. age 16 The transition IEP must already be in effect unreviewedWAC 392-172A-03090 — Definition of individualized education program. Postsecondary goals and the transition services needed to reach them must be in the IEP that is IN EFFECT when the student turns 16 — so the meeting that writes them happens before this point, not at it. Primary source pulled 2026-08-15: WAC 392-172A-03090(1)(k), WSR 21-19-065, effective 15 October 2021 — “Beginning not later than the first IEP to be in effect when the student turns sixteen, or younger if determined appropriate by the IEP team, and updated annually, thereafter.” The product’s own citation registry still carries this as UNREVIEWED, so the badge says so. The obligation is settled; the unverified part is our own citation record. ⚠ The marker moved with the reading. It previously read “transition planning begins” AT 16, which on a to-scale axis tells a district to start a year late — the rule is that the plan is already in force by then.
  3. age ~18 Rights transfer at the age of majority Statute34 CFR §300.520(a)(1)(i)–(a)(3) — Transfer of parental rights at age of majority Decision rights move to the student — and the district must STILL notify the parents of every Part B notice, permanently. A design that deactivates a parent contact at this point puts the district out of compliance on every notice it sends afterward. The marker is placed at 18 for the axis only. No citation in the registry establishes Washington's age of majority, so the number is illustrative and the label names the EVENT rather than an age.
  4. age 18 Graduation with a regular diploma StatuteRCW 28A.230.700 — purpose of diploma, elements of obtainment StatuteRCW 28A.230.710 — graduation pathway options A separate and independent terminating event — it ends eligibility whenever it happens, which is why it is drawn as a branch off the line rather than a point on it.
  5. age 22 Eligibility ends at the end of the school year in which the student turns 22 StatuteRCW 28A.155.020 (as amended by SSB 5253 — 2025 c 256 §3, eff. 2025-07-27) StatuteN.D. v. Reykdal, 9th Cir. No. 23-35580 (May 22, 2024) — published AN ENTITLEMENT, NOT A DEADLINE. A district may serve longer, never shorter, so it is drawn as a FLOOR that stays open to the right. Computing the end date from the birthday alone is the precise error that produced N.D. v. Reykdal: a student whose birthday falls mid-year loses the remainder of the year they were entitled to. On a to-scale axis THE MARKER'S POSITION ALSO ENCODES THE CLAIM, so a point at the birthday would be that error drawn instead of written. Primary source re-pulled 2026-08-15: RCW 28A.155.020, as amended by 2025 c 256 s 3 — “beginning at three years of age and concluding at the end of the school year in which the student turns 22 years of age.” The amendment followed N.D. v. Reykdal.
  6. age 22.6 Where the school year ends, exactly pendingAugust-31 boundary — PROPOSED rule (WSR 26-09-120) + RCW 28A.150.203(11) Where a school year ends for an exiting student is set by an August-31 test that the rule writes against the twenty-FIRST birthday. How it applies now the statute runs to 22 is not settled. Status PENDING, and the site previously overstated that. It read “an August-31 boundary is a PROPOSED rule, not one in force” — the mechanism IS in force; it is written against age 21, and what is open is its application under the age-22 statute. CLAUDE.md: follow it, do not cite it as law. It is on the axis because a district planning an exit needs to know the question is open.
  7. superseded The superseded age range conflictWAC 392-172A-02000 — FAPE age range (SUPERSEDED as to age) An earlier FAPE age range is still in the regulation text and is superseded as to age. It is drawn struck through because a district reading the WAC alone will find it. Status CONFLICT, re-verified against both primary sources 2026-08-15 and STILL LIVE. WAC 392-172A-02000 (WSR 21-19-065, effective 15 October 2021) reads “between the age of three and twenty-one years”; RCW 28A.155.020, as amended by 2025 c 256 s 3, reads “concluding at the end of the school year in which the student turns 22 years of age.” The regulation has not been amended to follow the statute. Drawn struck through, because a district reading the WAC alone will find the older range and nothing on that page tells them it has been superseded.
